Description

A kind of foaming hollow plastic fender product and production method
Technical field
The invention belongs to the crashproof fender of a kind of bank use and the stanchion product of land use, particularly a kind of foaming hollow plastic fender product and production method.
Background technology
Building stones commonly used, cement, mountain skin soil etc. were filled out the sea and are accomplished " mountain word " shape trestle when harbour was built, and formed building berth.For cutting apart, seawater does not flow the seawater water front, has destroyed original ocean current by the people, have a strong impact on and destroy the ecology environment in coastline, cause the harbour maritime interior waters rotten smelly, damaged halobiontic living environment, and man-hour is long, and the expense height has destroyed the ecology that the soil again when fetching earth.Adopt old-fashioned plastic fender at present, for example the patent No. is 02281015.3 " low foaming plastic fender ", and is therefore more crisp because of inner core is that the poly-alkene expanded material of high density constitutes, easy fracture when bearing greater impact power; And Heavy Weight, be difficult for floating; Rigidity is low, as flexible when doing pile.Node is difficult for handling when beam, post link, so solid product only is fit to be used as fender, is not suitable as the building stanchion and uses.
Summary of the invention
The purpose of this invention is to provide a kind of foaming hollow plastic fender product and production method, fender product is applied widely, saves timber, rubber and steel.In-use performance is good, improves service life, construction easily, and the reduction expense helps environmental protection.
Product engineering scheme provided by the invention is as follows: it comprises fender main body exocuticle, packed layer, it is characterized in that: in the fender main body, centre hole is set, between packed layer and centre hole, set gradually inner core skin, enhancement layer and inner core internal layer, and the crowded pull-rod of high strength is set in packed layer.
Above-mentioned center-hole diameter is of a size of external form diameter dimension or largest cross-sectional sized 0.4～0.5 times.
Above-mentioned main body exocuticle adopts the high-strength polyethylene material, and packed layer adopts low density polyethylene (LDPE) and high density polyethylene (HDPE) mixed foaming material, and its density is 0.75～0.82; The outer low-melting-point polyethylene plastic alloy material that adopts of inner core, enhancement layer adopts high strength glass fiber or steel wire grid cloth, the inner core internal layer adopts low density polyethylene (LDPE) and high density polyethylene (HDPE) composite material, and high strength is squeezed pull-rod and adopted high strength glass fiber material or screw-thread steel.
Product of the present invention is combined into harbour fender, crash barrier, building structural member by attaching parts.
Core producing method in foaming hollow plastic fender provided by the invention is hollow: it is characterized in that at first the inner core inner layer material being extruded the inner core internal layer through extruder, then through the typing of typing cover, cooling; Then through vertically glass fibre or steel wire feedway and registration device and floral disc cover vertical glass fibre or steel wire, laterally twine glass fibre or steel wire through wrapping machine again, described vertical glass fibre or steel wire feedway are along circumferential uniform a plurality of glass fibres or steel wire winding disc, and contact is by the damping fin of action of the spring on the integral body connection axial plane of steel wire winding disc; Carry out preheating through temperature booster, to melt temperature, it is outer field compound to carry out inner core internal layer, enhancement layer and inner core through composite machine head, cool off, cutting at last the hollow inner core product of fender.
The production method of foaming hollow plastic fender product provided by the invention: it is characterized in that earlier hollow inner core being carried out the end by inner core tack device cuts flat, carrying out hot melt by heat melting device then connects, by feed arrangement it is sent into preheating ring again, preheating temperature is 210-240 ℃, together send into composite machine head with stirrup then, carry out compound by composite machine head to hollow inner core, packed layer and exocuticle, compound after the typing of typing cover, again through the water cooling of the 20-40 of water collar degree, by the trailer coupling traction, cut into fender product at last.
Advantage of the present invention is: 1, and rubber fender, timber and junked tire on the desirable code head use attaching parts with the synthetic harbour fender of group of products, crash barrier, have saved timber and rubber.Use attaching parts to be combined into building structural members such as beam, post, save timber, steel, and handle easily when building structural members such as beam, post are chained.2, have excellent chemical stability, oxidative resistance, increased substantially impact resistance, flexible good, increased modulus of elasticity and rigidity; Thoroughly solved the difficult problem of steel reinforced concrete marine corrosion, improved service life exponentially.3, owing to adopt intermediate hollow, during as beam column, adopt corresponding attaching parts can prolong the three-dimensional link of two dimension arbitrarily, really reached the effect of plastics timbers, have the incomparable characteristic of solid product, enlarged the range of use of product.4, adopt product members construction of the present invention, not only shortened construction period, and saved expenditure on construction.Adopt product of the present invention to build up the bridge-type harbour, do not influence original ocean current direction, the coastline is penetrating, has realized the balance and the harmony of marine life, mankind's activity.5, use main material to be waste polyethylene, significantly alleviate the pressure of white pollution.The production process three-waste free discharge.
